"Interestingly enough, over the history of publishing, the really monster books, the ones that people talk about and remember for decades, were not easy-sell books. Often they would have fifty or more rejections before finding an editor willing to work for the book and a publisher took a chance. Then (when the book became a hit) it was called new and fresh and readers loved it.
And hard-sell books are flat impossible to get through agents in this new world. Agents give up submitting books after four or five rejections and often drop clients who force them to submit books that are not easy-sell books. (Remember, these days agents work for publishers, not writers.)
And even worse, writers allow agents to have them rewrite their work to make it more of an easy-sell, thus killing any original work in the book.
And when somehow that fresh idea, fresh book does get through an editor and gets published, (In this new world, more than likely indie published first), it will spawn (like a bad horror movie) thousands of “easy sell” books."
